摘　　要：This study aimed to determine the guide function of the number of gastrointestinal endoscope cases for the endoscopic submucosal dissection training of early gastric cancer.Three physicians in our center who began to learn ESD in July 2021 are selected and designate them as operators 1⁃3.The number of gastrointestinal endoscope cases performed by operators 1⁃3 before June 2021 was extracted,and the dissection speed among different operators in the ESD training stage was compared.The number of gastrointestinal endoscope cases performed by operator 1 was 3677,that by operator 2 was 4897 and that by operator 3 was 9249.The average dissection speed of operator 1 was 0.132 cm^(2)/min,operator 2 was 0.145 cm^(2)/min,and operator 3 was 0.174 cm^(2)/min.The dissection speed was ranked as operator 1<operator 2<operator 3,and one case of R0 resection was not achieved in both operator 1 and operator 2.Operator 3 achieved R0 resection in all 10 patients.With the increasing of number of gastrointestinal endoscope cases,the dissection speed and the stability of operation of endoscopists in the ESD training will increase.
